Forgot to write this in the bug but the problem doesn't occur in FF, Safari or Opera.

I can't repro on Mac 10.7, gc: Version 19.0.1085.0 canary, I scrolled down through the reported text and I see the currentTime increments as it should. 

- can you attack a screenshot? 
- also, can you try to repro on stable and canary? 

thank you

It definitely doesn't seem to be consistent on Canary. I have had it not happen at all, and then have seen it happen like in the two screenshots below.

Either way, I have one provided for stable and 2 for canary.

Hope this helps.

Second screenshot for Canary was incorrect. Playing around with it more and it definitely isn't consistent with the issue.

i've tried and tried, but still unable to reproduce the issue. 
do you have another url i can try it on? 
thank you

No I don't as that is a specific test case I wrote to try and separate out the issue from the application I am working on that is experiencing the problem.

I'm wondering if it is a hardware issue then. I'll try to get someone to try it on Canary and see if it persists.

Updated the test to make the erroneous results more obvious.

schranz.m@ thank you very much for modifying the test, I was able to reproduce the issue on Ubuntu 10.04 stable and canary builds, so is on Mac 10.7 with stable and canary builds. 

This is not a regression.

Is this still an issue? The repro link is down.

Archiving as the repro link is no longer reachable. If this issue is still repro'ing for you, schranz.m@, please activate & post latest chrome version (ideally M33 or M34) and repro link.
